ORE PULVERIZER AND CONCENTRATOR.

Specification of Letters Patent.

ratenteol April. 23, 1907.

Application led April 27, 190.` Serial No. 313,926.

.To @ZZ whom it may concern:

Be it known that I, OBADIAH K. Mc- CUTcr-IEON, a citizen of the UnitedStates, re-

.siding at Pittsburg, in the county of Alleimprovement in orepulverizers and concentrators, and is more particularly adapted to thecrushing and extracting of free-milling gold ores, although other oresof a harder formation may be quickly reduced to a pulverized state in mydevice.

In the accompanying drawings, forming a part of this specification, Ihave shown several views of my invention.

Figure 1 is a sectional view of the invention; Fig. 2, a top plan view,partly broken away. Fig. 3 is a cross-sectional view taken on line 3 3of Fig. l. Fig. 4 shows two views of the securing-bolt, and Fig. 5 is asimilar view of one of the beaters used to pulverize the ore.

Numerals of reference designate like parts throughout the differentviews, l being the framework forming the body portion of the pulverizer.Inside of this framework is arranged a steel trough or receptacle 2, inwhich the ore is pulverized and washed with water, thus separating thegold from the ore. rihe discharge end of the pulverizer is slightlyraised above the opposite end, being about one-third of an inch to thefoot, and the gold which is being separated from the ore during thepulverizing process will naturally settle to the lowest level, which inthis device will be at the receiving end of the machine. A largevpercentage of the gold will therefore settle or concentrate on the.bottom of the machine at the lowest point of the trough while thepulverized ore is being carried forward and out of the discharge end.

Extending longitudinally the entire length of the machine is a cylinder3, which is made to revolve on gudgeons 4 4l, mounted in each end ofsaid cylinder and secured thereto.

These gudgeons 4 4 are in turn operatively mounted in suitable bearings5 5 adjacent each end of the pulverizer. Arranged through the cylinder 3at stated intervals are a series of securing-bolts 6 6, on one end ofeachbolt being an enlarged portion for receiving the bif'urcated end ofthe beaters 7 being secured thereto by a bolt or other suitable means.On the opposite end of each bolt 6 is a nut 8, by means of which thebeaters 7 may be drawn tight against the cylinder 3 and held thus inthis position. It will also be seen that the lower end of each beater ishollowed out and cut on a slight angle sufficient to conform to thecontour of the cylinder.

The securing-bolts 6 6, passing through the cylinder 3, are so arrangedthat the beaters 7 willy be held at an angleand inclining toward thedischarge end of the pulverizer for the purpose of gradually moving thecontents of the receptacle 2 forward during the process of crushing. Anordinary packing-gland 9 is arranged over the gudgeons 4 at each end ofthe pulverizer.

At the top of one end of the machine is an ore-receiver 10, whichconnects with a sluice-box 10, and on the gudgeon 4 is mounted apower-wheel 11.

A spout 12 is arranged at the discharge end of the machine, out of whichthe pulverized ore is expelled.

On top of each bearing 5 is an oil-cup 14.

The ore is carried or fed into the pulverizer by water through a seriesof troughs-or sluiceboxes any desired distance, and while in transitthis water is softening the ore and decomposing it readyh for thepulverizing process. One of the essential points 'of advantage in myinvention is the fact that the same water that is being utilized tocarry the ore to the pulverizer is likewise used to wash the ore, aid inthe process of pulverization, and carry the ore out of the machine. Theposi-- tion of the feed-pipe l0 directly over the cylinder 3 will makeit possible for the rapidlyrevolving beaters 7 7 to crush the ore andcommence the process of pulverizing the instant that said ore isadmitted into the trough 2. These beaters 7 7 are constructed in sizetwo and one-half inches by three inches by seven inches, making themsufliciently strong to reduce the hardest of ores, and when the cylinder3 is made to revolve at a very rapid speedabout two hundred and IOO IIO

^ scribed, and by the time it is ready to be expelled out through thespout 12 it is reduced to a muddy consistency.

In case any of the beaters should become loose or damaged they caneasily be reached in order to be tightened or replaced by simply raisingthe top of the machine.

A curved rim or block 15 about twol and one-half inches high is placedinfront of the intake to the spout 12, which will act as a dam and holdback any of the gold vthat might otherwise pass through said spout.

Having thus fully shown and described my invention, what I claim as new,and desire to secure by Letters Patent, is*

1. In a pulverizer and concentrator, a suitable receptacle designed toreceive water and ore, a cylinder j ournaled longitudinally of thereceptacle, means for rotating the cylinder; the said cylinder having aseries of diagonally-disposed openings therethrough, bolts in saidopenings having flattened heads extending longitudinally thereof andprovided with apertures, means for securing the bolts in place, beatersapplied to the'bolt-heads, said beaters consisting of blades havingbifurcated inner ends to receive the heads of the bolts, and havingtransversely-disposed apertures adapted to register with the aperturesof the bolts, and securing means engaging the bolts andgbeaters.,

rections at right angles to the recessed por* tion to lie longitudinallyof the cylinder, the bevel of the ends being at right angles to thepitch of the apertures in the cylinder.

3. In a pulverizer and concentrator, a suitable receptacle, a cylinderjournaled therein, means for rotating the cylinder, said cylinder havingdiagonally-disposed apertures, bolts having shoulders in steppedrelation to engage the periphery of the cylinder, the said bolts havingflattened heads extending beyond the periphery of the cylinder, beatershaving bifurcated ends to receive the heads of the bolts, said innerends being transversely recessed and beveled in directions at rightangles to the recesses, means for securing the beaters to the bolts, anda suitable supply-hopper and dischargeespout for the receptacle.

In testimony whereof I affix my signature in presence of two witnesses.
